Polygon r and polygon s are similar. the perimeter of polygon r is 192 cm, and the perimeter of polygon s is 36 cm. if one side of polygon s is 3 cm, what is the length of the corresponding side in polygon r?

Respuesta :

1.815 cm.
Create a proportion of the perimeter and the side lengths with r values in numerator and s values in the denominator.
[tex] \frac{196}{36} = \frac{3}{x} [/tex]
cross multiply 
196x=108
divide both sides by 108
x=1.815
